Just judging from the sheer volume of social media I consumed all day yesterday, the fan base here is in “quit on the 2009 season” mode. The lofty expectations following a rookie campaign for John Harbaugh and Joe Flacco that ended in the AFC Championship Game led all of us in the Charm City to feel as though this year would somehow be better.

Well, we’re halfway through the race and things haven’t gone according to the best laid plan.

The Ravens have lost four of their last five, including yesterday’s turd in Cincinnati. The team, overall, just hasn’t been as good as advertised in many ways. The Bengals have now embarrassed the Ravens twice in four weeks en route to sole possession of the AFC North lead and have earned the right to crow.

While yesterday’s loss certainly felt like more of a beatdown than the final score — and we’ll get to Steve Hauschka’s missed kick in a minute — the NFL only counts one thing en route to a playoff berth in the tournament: wins. And right now, at 4-4, this isn’t going to get it done.

I could make excuses for all of the other three losses — and losing in the waning seconds on the road to New England and Minnesota doesn’t make you a bad team. But the pair of losses to the Bengals has been illuminating, especially when you consider Marvin Lewis’ recipe for building a team with a 6-2 start.

The Bengals have just about everything you’d want — a world-class quarterback with a world-class wide receiver and a running back who runs like Jamal Lewis with a line that’s got a nasty streak. On defense, they’ve built through a young linebacking corps (sound familiar?) and a pair of first-round cornerbacks who allow the safeties and linebackers to play hardball with the pass rush. Oh, yeah — they also arguably have the best kicker in the sport.

The Ravens, as was in full display yesterday, are sorely lacking in various departments but especially the ability to get off the field consistently on 3rd down on defense. It’s been a defensive franchise for the better part of 11 seasons. All good things must end and the 2009 defense is not up to “Play Like a Raven” standards.

Is that Greg Mattsion’s fault? Is that because of the clear falloff at the cornerback position? Is it not having Rex Ryan? Is Bart Scott missed that much? Is Ed Reed OK? Will Haloti Ngata be injured all year?

The entire secondary was beaten in coverage during the first half and the penalties were dreadful. All over the field. Ray Lewis is still the Ravens best player when Ngata is not dressed and that speaks volumes.

The first three losses were “excused” in my opinion. Yesterday, however, did a lot to expose the Ravens as a team that’s pretty good but not a serious playoff contender, especially not with that secondary and lack of pass rush.

Sure, Haloti Ngata’s absence needs to be factored into the equation in the Bengals debacle, but the Ravens have sufficient depth at that position and I’m not sure Ngata would’ve been a difference maker in the outcome yesterday in Cincinnati.

As for the offense, Joe Flacco just was not good enough yesterday, nor was the offensive line, which played its worst game of the season. Penalties? All over the place and ill-timed. Productivity? How about making their first third-down conversion in the fourth quarter? That’s just putrid, unacceptable and not worthy of the NFL playoffs.

They didn’t run well. They didn’t pass well. They were out of sync all day and Flacco looked bewildered during his short stints in the first half. Flacco has now dropped five straight to teams led by Ben Roethlisberger and Carson Palmer.

Derrick Mason and Ray Lewis declined to comment after the game yesterday but I’m sure they’ll have something to say on Wednesday at The Castle.

Harbaugh did his usual tap dance around any tough questions from the media — (memo to John: denying that the team doesn’t tackle well is laughable at this point) — but it’s easy to do what you want when you’re in the AFC Championship Game and things are going better than advertised.

But when the team is a disappointing 4-4 at the turn and the one decision that’s truly pinned to Harbaugh’s special teams badge of expertise — the banishment of kicker Matt Stover in the offseason — costing the team team parts of two of the losses, the questions are only going to get tougher around the head coach and around Steve Hauschka.

This team was supposed to go to the playoffs. This team was supposed to be a Super Bowl contender. The “upgrades” of the offseason were well-calculated and the draft went well. The Ravens and the fanbase were not prepared to be swept by the Bengals and be 4-4 at the turn.

All eyes will now turn to Cleveland, where the Ravens most certainly will awaken eight days from now at 5-4. Right? We can only hope…

The Ravens have amassed four losses and haven’t yet seen the Steelers, the Colts or a frigid December night at Lambeau Field and a West Coast trip to the zoo in Oakland in early 2010. There’s a lot of football left to be played.

The Ravens will sort this out on the field. They need to go 6-2 to have a chance. They need to go 7-1 to be assured of a spot.

If they do it, they’ll be good enough. If they lose two more times to the Steelers, they’ll be playing golf on Jan. 4th and deservedly so.

And if that happens, John Harbaugh’s gonna have a lotta ‘esplainin’ to do at that postseason press conference while he sits next to Steve Bisciotti and the Steelers and Bengals are still playing football…

Things like:

What really happened in the decision to replace Matt Stover with Steve Hauschka?

What really happened with Chris McAlister and how did we get sold that Domonique Foxworth and Chris Carr are upgrades?

Why all the penalties?

Where is the pass rush?

Where is Willis McGahee?

Where is the urgency on offense when the team is down two scores with three minutes left?

Of course, Harbaugh doesn’t really like the tough questions but they’re coming. It’s a tough job. It’s been a lot of fun, this honeymoon of riches and a great start to his era in Baltimore. Getting to the AFC Championship Game as a rookie head coach indeed buys you a hall pass for a while.

I have a feeling a lot of that ended yesterday, with a sweep to the Bengals and a 4-4 record at the turn.

But, as Brian Billick would no doubt tell him, these Monday mornings aren’t a whole lot of fun when the town gets disappointed and the team plays poorly.
